Benjamin Franklin knew he was smart — smarter than most of his peers — but he was also intelligent enough to understand that he couldn’t be right about everything. That’s why he said that whenever he was about to make an argument, he would open with something along the lines of, “I could be wrong, but…” Saying this put people at ease and helped them to take disagreements less personally. But it also helped him to psychologically prime himself to be open to new ideas.
